DirtMechanic, if it still worries you, here is a list of foods that are particularly high in psoralen.
https://www.healwithfood.org/foods-that-contain/psoralen.php Overall, I agree with what others have said, all things in moderation.
It is also being used to help fight certain types of cancer, which I find interesting. Causes one, but fights another, that's just weird.
Reporting in the Feb. 14, 2014 issue of the journal PLOS ONE, the researchers detail how psoralen blocks the signaling pathway of the HER2 receptor, which is overproduced in 25 percent of breast cancers, plus ovarian, gastric and other solid tumors. When HER2 is overproduced, it fuels uncontrolled cell growth, leading to an aggressive form of cancer. Psoralen shut down this process in experiments using HER2 overexpressing breast cancer cell lines.

Lesson learned: The body is super, super efficient.
The body is almost frighteningly efficient!
I recently had problems with one of my eyes, and they prescribed steroid drops and also drops to dilate the pupil. My vision was blurred for a while - because the pupil was dilated. (Like a camera out of focus.) When I commented on this, the ophthalmologist became quite concerned, and told me to ...
... keep an eye on it, because if my body decided the eye was not working, it would basically shut it off. This is also why they cover the good eye on children with "lazy eye." They have to train the body to
use that eye.
Another example would be excessive use of fiber supplements or laxatives. If you use either for too long, the body will "forget" how to work on its own, and you'll never be regular without them.
Next someone will say bacon grease is bad for you. In Texas, them's fightin' words!
In Ohio, too!
Mmm, cabbage and potatoes and onions, fried in bacon grease. (Swoon!
